You are right that CryEngine doesn't use OpenGL it seems, but at least they are pretty close with PSGL and they also seem to be working on Linux support.

Crytek apparently read your comment ;) and an hour later announced official support for Linux.

PSGL is barely OpenGL, it is OpenGL ES 1.0 with Cg for shaders.
Not much that code is portable across the respective OpenGL flavors.
Wikipedia is wrong about the usage of OpenGL on consoles.
Crytek uses libGCM on PS3, not PSGL.
